Iris-mini and Iris-pro are the strongest open-weight search agents in their class
AllSpark's Iris agents top open-weight benchmarks — and transfer surprisingly well to tasks they never saw.

Why it matters
New open-weight search agents (Iris-mini, Iris-pro) deliver frontier-class performance in their size classes and show unexpected generalization to tool use and office work — a significant capability checkpoint for practitioners evaluating open alternatives to proprietary agent platforms.

Publisher excerpt: The AllSpark team has released Iris-mini and Iris-pro, two open-source search agents built on Qwen models that lead benchmarks among open-weight models in their size classes. According to the paper, the training data and models also improved performance on tasks they were never trained for,…
